Backend API libraries

Viimeksi muokattu: , 22. maaliskuuta 2024

In order for a software application to interact with the Ethereum blockchain (i.e. read blockchain data and/or send transactions to the network), it must connect to an Ethereum node.

For this purpose, every Ethereum client implements the JSON-RPC specification, so there are a uniform set of methods that applications can rely on.

If you want to use a specific programming language to connect with an Ethereum node, there are many convenience libraries within the ecosystem that make this much easier. With these libraries, developers can write intuitive, one-line methods to initialize JSON-RPC requests (under the hood) that interact with Ethereum.


It might be helpful to understand the Ethereum stack and Ethereum clients.

Why use a library?

These libraries abstract away much of the complexity of interacting directly with an Ethereum node. They also provide utility functions (e.g. converting ETH to Gwei) so as a developer you can spend less time dealing with the intricacies of Ethereum clients and more time focused on the unique functionality of your application.
